PIPE-HANGER.

SPECIFICATION forming part of Letters Patent No. 471,348, dated March 22, 1892.

Application filed December 15, 1891- Berlal No. 415,153- (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN COLLIS, a citizen of the United States, residing at Des Moines, in the county of Polk and Stateof Iowa, have invented a new and useful Improvement in Pipe-Hangers, of which the following is a specification.

Myinvention relates to an improvement in pipe-hangers for use particularly in buildings for suspending horizontal steam or other pipes under ceiling-beams.

My object is to provide a pipe-hanger of an improved construction which will permit the pipes to expand and contract longitudinally without material strain upon the hanger.

In the drawings, Figure l is a broken view in elevation showing my improved hanger in operative position upon a metal ceiling-beam, parts of the hanger being shown in section for the purpose of illustration. Fig. 2 is a section on line 2 of Fig. 1 and viewed in the direction of the arrow; Fig. 3, a broken plan view taken from line 3 of Fig 2, looking downward; and Fig. 4, a View, partly sectional, of the upper portion of my improved hanger, showing the fastening means employed for securing it to a wooden ceiling-beam.

A is a single track for the grooved wheelB. In the construction shown in Fig.1 the track A is supported between side bars 1. t, which are shaped, as shown, to extend at their upper end portions along the flange of an I- beam X, and toward their lower end portions they are flared outward and provided with inwardly-projecting lugs s. The track A is a hollow tube adapted at its ends to receive the lugs 8. Just below the plane of the under surface of the I-beam X the side barst are provided with openings to receive a tiebolt 4', carrying a nut r. The grooved wheel Bis provided with a shaft, which at its opposite ends is engaged by and affords a hearing for a stirrup B. The stirrup B extends below the track A and terminates in a threaded socket r O is a yoke provided in its upper face with a threaded socket q and having ears or lugs 19, recessed in their upper sides to produce sockets 19'.

D D are the two side pieces or halves of a stirrup, curved throughout nearly its entire extent. The upper ends of the side piecesD are flanged to produce fiat opposing extensions 0 0, provided with openings 0', adapted to slip over the ears p and rest in the sockets .1). The lower end of one of the side pieces D is bifurcated, as shown in Fig. 3,130 receive the lower flattened end of the other side piece D. The two side pieces are fastened together at their lower intermeshing ends by a cotter n, which passes through coincident openings in the said side pieces. Screwed at opposite ends respectively into the sockets r and q is is a rod m.

The pipe to be supported extends through the stirrup D in a line parallel with the track A. Longitudinal expansion or contraction of the pipe will cause the parts below the track A to move back and forth upon the wheel B, and thus prevent material friction.

In the construction shown in Fig. 4 the track A consists of a bolt passing through openings in the lower end portions of a stirrup-piece Z. At the'oenter of its upper side the stirrup Z is provided with a lag-screw k, at which it may be secured to a wooden beam Y.

The distance of the suspended pipe from the supporting-beam X or Y may be regulated by providing a longer or shorter connecting-rod m. I

My improved hanger constructed as de= scribed prevents injury to the hanger from the longitudinal movement of the pipe as it expands and contracts, and it furthermore affords a strong, durable, and comparatively inexpensive device for its purpose.

tVhile the construction shown and described is the one I prefer to employ, it may be modified in the matter of details of construction without departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a pipe-hanger, the combination of a track and means for attaching it to an over a IOO to travel thereon, a stirrup suspended from the wheel and provided with a socket, and a rod fastened to the stirrup at said socket and carrying the pipe-engaging portion of the 5 hanger, substantially as described.

3. In a pipe-hanger, the combination, with the pipe-engaging portion thereof, of a track, a Wheel mounted uponthe track to travel thereon, from which the said pipe-engaging portion is suspended, and means for securing IO the track to the flanges of a beam, comprising the side bars 25, tie-bolt 'r, and projections s, engaging the opposite ends of the track, substantially as described.
